Dual Encoder-specific

ENS (main): Hiperface (digital), 1Vpp (analog), TTL (square wave), compatible with Yaskawa IndraDyn and common motors.

EN2 (second): EnDat 2.1 (digital), 1Vpp (analog), TTL (square wave), independent interface, supports dual feedback redundancy / master-slave synchronization.

Power supply: Both are DC11.6V/300mA.

III. Configuration highlights (The value of dual encoders)

ENS + EN2 dual encoders working simultaneously

Main encoder (ENS): Connects to the built-in encoder of the motor, performing speed / position closed-loop.

Second encoder (EN2): Connects to external position feedback (such as grating ruler, driven axis encoder), achieving full closed-loop control / master-slave synchronization / redundant backup.

S3 (SERCOS III)

High multi-axis synchronization accuracy, suitable for high-speed联动 equipment such as machine tools， packaging， and printing.

S2 (STO safety)

Standard safety torque off， meets mechanical safety standards， no additional safety module required.

FW (pre-installed firmware)

Factory pre-programmed firmware， ready for use upon power-on， saving engineering time.

IV. Application scenarios

Full closed-loop control for machine tools (motor encoder + grating ruler dual feedback).

Master-slave synchronization / tension control (such as roll materials， printing， textile equipment).

High-reliability redundant system (dual encoders as backups to prevent feedback failures).

Multi-axis联动 CNC machine (SERCOS III bus synchronization).

Automation production lines requiring STO (SIL3) safety function.
